Hello, so I have been doing some research of Red Eyed Tree Frogs and have a couple questions... I will be doing a Vivarium and wanted to know what kind of light to use in a 18x18x24? It will host live plants so it will need UVB ect.. I was looking at the Exo Terra natural light 2.0 and it comes in 2 different watts, 13 and 26 watts! Now which watts would be good to purchase?? I am open to everyone’s opinions and suggestions!! Just want to make sure I have a beautiful thriving vivarium for my little frogs and a healthy one too! Also how long would I leave the light on for the plants ect...
